| Abstract: | A mathematical model of CNC machine tool servo system which is considered as the research object,is created in this paper and also a sliding mode self-adaption controller is designed combined with LuGre friction model.The parameters of the PID sliding model surfance can be estimated online.The asymptotic stability of the system is proved by Lyapunov function.Finally,the MATLAB simulation experiments and physics experiments further show that the system has good tracking performance. |
